FSL-751 LASER Smoke Detector

The Notifier FSL-751 VIEW® Laser Detector is a revolutionary advance in early warning smoke detection technology. The unique design of this detector, combined with enhanced intelligent sensing algorithms in the Notifier AFP-300, AFP-400, NFS-640, NFS2-640, NFS-320, NFS-3030 or NFS2-3030 control panels, for smoke detection sensitivity that is up to 50 times higher than present photoelectric technology. Because of this high sensitivity, the FSL-751 can provide very early warning of slow smouldering fires. Its performance is comparable to present aspiration technology, at a substantially lower installed cost.

The FSL-751 uses an extremely bright laser diode, combined with special lens and mirror optics (U.S. patent pending), to achieve a signal-to-noise ratio that is much higher than traditional photoelectric sensors. In addition, the tightly focused light beam, combined with the intelligent sensing algorithms, allow the system to differentiate between dust and smoke particles. Because of this differentiation, the FSL-751 can be set to extremely high sensitivity, yet can reject false signals caused by larger airborne particles such as dust, lint, and small insects.

The FSL-751 is an intelligent (analog/addressable) detector. Using CLIP mode, up to 99 FSL-751 detectors may be installed per loop. On Flash Scan® systems (NFS-640/NFS2- 640/NFS-320/NFS-3030/NFS2-3030), up to 159 addresses are available. The FSL-751 may be mixed in any combination with other Notifier intelligent sensors on the same loop and is quickly installed using the panel auto program feature. The FSL-751 has dual bi-colour LEDs, which blink green in normal operation and illuminate steady red in alarm. Flash Scan® (U.S. Patent 5,539,389) is a communication protocol developed by Notifier for high speed communication between analog intelligent devices. Intelligent devices communicate in a grouped fashion. If one of the devices within the group has new information, the panel CPU stops the group poll and concentrates on single points.

The net effect is response speed greater than five times that of other protocols. Using the enhanced intelligent sensing algorithms, the intelligent sensing system provides drift compensation (meeting UL requirements as a calibrated sensitivity meter), maintenance alert (3 levels), selection of 9 alarm levels and 9 pre-alarm levels, and report of drift compensation used and recent peak values. The system includes a self-learn sensitivity adjustment to set the pre-alarm level just above the peak levels sensed over long periods of time for each detector’s actual environment. The system includes multi-detector algorithms that permit one sensor to consider readings from adjacent sensors to provide faster detection of fires.
